Abstract
Description
Technical Field
[0001] This utility model relates to an anal canal drainage and fixation device, belonging to the field of medical auxiliary equipment technology. Background Technology
[0002] With advancements in surgical techniques and instrument functionality, the rate of sphincter preservation after rectal cancer surgery has significantly increased. However, this has also led to a marked rise in the incidence of anastomotic leakage, resulting in unplanned secondary surgeries, increased mortality, and reduced long-term quality of life. Studies have shown that indwelling anal cannulas can reduce the incidence of postoperative anastomotic leakage by lowering rectal pressure. Currently, the methods for fixing the anal canal are simplistic and crude, using sutures to fix the anal canal to the perianal skin. This leads to problems such as perianal skin traction pain, bruising at the suture fixation site, and decreased sleep quality. These issues not only affect the patient's hospital experience but also hinder their willingness and actions to participate in accelerated postoperative recovery.
[0003] While simply fixing the anal canal to the perianal skin with sutures provides some stability, it significantly reduces patient comfort, sleep quality, and causes noticeable traction pain. Patients become reluctant to move around in bed or get out of bed, increasing the incidence of venous thromboembolism and causing secondary harm. The perianal skin may develop ecchymosis due to puncture, and sometimes anal secretions may leak out, leading to incontinence dermatitis. Utility Model Content
[0004] The purpose of this invention is to address the aforementioned problems by providing a reasonably structured and easy-to-use anal tube drainage fixation device.
[0005] To achieve the above-mentioned utility model objectives, the technical solution adopted by this utility model is as follows: an anal canal drainage and fixing device, characterized in that it includes a first half patch and a second half patch;

[0014] The material of the first half patch and the second half patch is the material of the Mio ostomy base plate of the Coloplast company.
[0015] The first suture is fixed on the first half patch by glue, and the second suture is fixed on the second half patch by glue.
[0016] The utility model discloses a reasonable structure, through the utility model, when using: the first half patch and the second half patch are pasted on the perianal skin through the adhesive, the anal tube is taken out from the circular anal tube through hole formed by the first semicircular notch and the second semicircular notch, then through the first suture and the second suture, the anal tube is wound and knotted to play a fixing role, avoids the anal tube to slip off, realizes the anal tube fixation.
[0017] In the utility model, the first half patch and the second half patch are pasted on the perianal skin, avoid the secondary injury to the patient, avoid the traction pain, improve the patient's comfort, improve the patient's willingness and behavior to participate in the postoperative rehabilitation, the suture (the first suture and the second suture) fixed on the first half patch and the second half patch is wound and knotted with the anal tube to play a fixing role, avoids the anal tube to slip off.
[0018] Preferably, the side of the first half patch with adhesive and the side of the second half patch with adhesive are both pasted with adhesive protection paper, which plays a role of protecting the first half patch and the second half patch when not in use, when in use, first, the adhesive protection paper is torn off, then the first half patch and the second half patch are aligned with the anal tube and pasted on the perianal skin, the first half patch and the second half patch are pressed to make them completely fit, finally, the suture (including the first suture and the second suture) is wound and knotted with the anal tube.
[0019] Preferably, the material used by the first half patch and the second half patch is the material of the Mio ostomy base plate of the Coloplast company, which has the characteristics of close fitting, flexible and body-adapting, leakage prevention and not easy to fall off.
[0020] Preferably, removal lugs are arranged on the first half patch and the second half patch, which facilitate the removal of the first half patch and the second half patch from the perianal skin after use.
[0021] Preferably, the first half patch and the second half patch are both semi-elliptical; the first half patch and the second half patch together form an ellipse; the first semicircular notch is arranged on one side of the straight line of the first half patch, and the second semicircular notch is arranged on one side of the straight line of the second half patch; when the first half patch and the second half patch are spliced, the side of the straight line of the first half patch is spliced with the side of the straight line of the second half patch, and the first semicircular notch and the second semicircular notch form a circular anal tube passing hole.
[0022] Through the specific design of such a shape, the first half patch and the second half patch are better attached to the perianal skin, and at the same time, it is more convenient for the anal tube to pass out of the anal tube passing hole, and it is more convenient for the first suture and the second suture to be knotted with the anal tube, so as to realize the fixation of the anal tube.
